Whakaoti i te 9=x*x

$$9 = x \times x$$

Whakaoti mō x

$$x=3$$

$$x=-3$$

Ngā Upane mā te Kimi Pūtakerua

Whakareatia te x ki te x, ka x^{2}.

$$9=x^{2}$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$x^{2}=9$$

Tuhia te pūtakerua o ngā taha e rua o te whārite.

$$x=3 x=-3$$

Ngā Upane e Whakamahi ana i te Tikanga Tātai Pūrua

Whakareatia te x ki te x, ka x^{2}.

$$9=x^{2}$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$x^{2}=9$$

Tangohia te 9 mai i ngā taha e rua.

$$x^{2}-9=0$$

Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, 0 mō b, me -9 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

$$x=\frac{0±\sqrt{0^{2}-4\left(-9\right)}}{2}$$

Pūrua 0.

$$x=\frac{0±\sqrt{-4\left(-9\right)}}{2}$$

Whakareatia -4 ki te -9.

$$x=\frac{0±\sqrt{36}}{2}$$

Tuhia te pūtakerua o te 36.

$$x=\frac{0±6}{2}$$

Nā, me whakaoti te whārite x=\frac{0±6}{2} ina he tāpiri te ±. Whakawehe 6 ki te 2.

$$x=3$$

Nā, me whakaoti te whārite x=\frac{0±6}{2} ina he tango te ±. Whakawehe -6 ki te 2.

$$x=-3$$

Kua oti te whārite te whakatau.

$$x=3 x=-3$$
